Features• Rail-to-rail input and output• Low noise: 9 nV/√Hz• Low distortion• High output current: 80 mA (able to drive 32 Ω loads)• High-speed: 4 MHz, 1 V/μs• Operating from 2.7 to 12 V• Low input offset voltage: 900 μV max. (TS922A)• ESD internal protection: 2 kV• Latch-up immunity

Applications• Line drivers and actuator drivers• Portable speakers• Instrumentation with low noise as key factor• Multimedia systems and portable equipments

DescriptionThe TS922 and the TS922A devices are rail-to-rail dual BiCMOS operationalamplifiers optimized and fully specified for 3 V and 5 V operations. These deviceshave high output currents which allow low-load impedances to be driven.

Very low noise, low distortion, low offset, and a high output current capability makethese devices an excellent choice for high quality, low voltage, or battery operatedaudio systems.

The devices are stable for capacitive loads up to 500 pF.

1. All voltage values, except the differential voltage are with respect to network ground terminal.2. The differential voltage is the non-inverting input terminal with respect to the inverting input terminal. If Vid >

±1 V, the maximum input current must not exceed ±1 mA. In this case (Vid > ±1 V), an input series resistormust be added to limit the input current.

3. Do not exceed 14 V.4. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-

circuits on all amplifiers. These values are typical.5. Human body model: 100 pF discharged through a 1.5 kΩ resistor between two pins of the device, done for

all couples of pin combinations with other pins floating.6. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between

two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples ofpin combinations with other pins floating.

7. Charged device model: all pins and plus package are charged together to the specified voltage and thendischarged directly to ground.

8. There is no short-circuit protection inside the device: short-circuits from the output to VCC can causeexcessive heating. The maximum output current is approximately 80 mA, independent of the magnitude ofVCC. Destructive dissipation can result from simultaneous short-circuits on all amplifiers.
